I have to ask, who actually pays these prices? I can only think of 2 possibilities: truly desperate people; or investors who think it will be worth even more in the future and this is just an investment.

This is someone's memories being sold off. The more I stare at that photo, the more questions I have. Are any of these people still alive? Did they buy their clothes at Sears? Are they still Star Wars fans? Is that a ghost in the window? Is that a glass of beer on top of the tv?
